Specification of Letters Patent.

Patented June 9, 1908.

Application filed August 81, 1907. Serial No. 890,925.

To all whom it may concern:

Be it known that 1, CHARLES W. Nssnnns, a citizen of the United States,residing at Atlantic, in the county of Cass and State of Iowa, haveinvented a certain new and useful Vehicle Pole, of which the followingis a specification.

Poles for light vehicles are usually formed complete of a single pieceof hickor or other strong and tough wood, the rear our of which is bentby a steaming process so as to elevate the pole ody about a oot abovethe rear end thereof. These poles are very expensive, and are alsofrequently broken.

My ob'ect is to provide a vehicle pole of substantially the same sizeand shape as the vehicle oles now in use, and to construct the same 0metal at the part in which the curve occurs, and of thin metal filledwith wood at the straight body of the ole, and thus form a vehicle poleof light weight and strong and durable construct1on,= at a cost muchless than the cost of the wooden vehicle poles now in use, and also torovide a pole of this kind that is much less liable to breakage than thewooden poles now in use.

My invention consists in the construction, arrangement and combinationof the various parts'of the device, whereby the obiects contemplated areattained, as hereina ter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawings, in which- Figure 1 shows aplan view of a vehicle pole embod ing my invention. Fig. 2 shows anenlar e detail sectional view on the line 2-2 of ig. 1, and Fig. 3 showsa longitudi-- nal-sectional view through the rear portionol' the vehiclepole embodying my invention on an enlarged scale.

Referring to the acconipanyin drawings, I have first described thecurvet portion at the rear of the pole. This portion is preferablyformed complete of one iece of metal, on it is also formed hollow. hebody )ortion thereof is indicated bv the numeral l0, and at its rear endis a top brace 11 and a bottom brace 12 at ri ht angles to said bodyportion, to receive etween them the wooden pole bound 13, which latteris of the ordinary construction. The u mm or forward end of the bodportion 1 is provided with a straipht internal opening and projcctinybeyou the upper portion t ereo is a rcin orcin. strap 14, and on thebottom is another reinforcing strap 15. Formed on the top of the forwardend of the part 10 is a raised lug 16 having a vertical opcnim 17extended through it, and also through the bottom portlon of the part 10to receive a king bolt. A king bolt strap 18 is provided with itsforward end above the opening 17, and its rear end connected by a bolt19 with the body portion 10. Two brace rods 20 are provided with theirrear ends connected to the outer ends of the pole hound 13, and theirforward ends connected by a bolt .21 with the forward )ortion of thepart 10, and by a bolt .22 with t to forward portion of the pole beyondthe body portion.

' The forward )ortion of the pole is formed complete of a ollow sheetmetal tube 23 ta ered from its rear to its forward end, and filiiad witha wooden pole filler 24. This pole filler 24 also extends rearwardlyinto the ody portion 10, as clearlv shown in Fig. 3, the rear end ofsaid filler being curved at its top to conform to the curved interior ofthe part 10, and being straight along its bottom so as to project as faras possible into the curved portion of the part 10, without the woodbein curved itself. A bolt 25 is extended tlirough the forward end ofthe strap 14 and throu h the sheet metal tube 23 and the wooden iller 24to connect these parts together.

In assembling my improved vehicle polo, I first form the sheet metalcover 23. l thou force the wooden tiller 24 into it with the rear end ofthe filler pro'ecting be ond the part 23. This wooden lillcr may beformed of cheap and inexpensive wood that docs not need to haveany greatamount of strength or toughness, but is simply for the pur mat ofpreventing the shoot metal cover 23 l lom becoming bent or buckled whensubjected to strains. I also preferably force the wooden filler into thecover 23 with a considcrablc dc rec of pressure so that. it iltsaccurutciv, an thus prevents the sheet metal covcr .23 from becomingindented or buckled. 1 then place the vertical rcar cud of the woodcuiller into the metal body portion It), as shown in Fig. 3, and theninsert the various bolts for conncctin the straps l4 and 15 and thebraces 20 wit 1 the two parts of the vehicle pole. By this arrangementthe curvcd portion of the vehicle pole is made doubly strong. The upperbody is also made stronger than the wooden polo body of the same size,and yet is of comparutivcly light. weight, and at the same time is morerigid than a wooden pole. By extending the straps 14 and 15 over thesheet metal cover 23, and by having the braces 20 connected with boththe parts 10 and 23, and also b havin v the wooden filler projectthrougi both t 1e parts 10 and 23, the vehicle )010 is made stronger atthe joint between t is forward -and rear sections than at any otherpoint. In this way I provide a vehicle pole that is stronger and moredurable than a pole of similar size made out of the best wood, and at acost far less than the cost of wooden vehicle poles, and I also providea pole that is of on y slightly greater weight than the wooden ole, theweight however, being contained a most wholly at the rear of the polewhere it does not bear as heavily upon the draft animals as it would ifthe entire polo were made of metal.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, therefor, is

1. An improved vehicle pole comprising a hollow rear pole section,curved upwardly and then forwardly from its rear end, and formed withstraps on its forward end at its top and bottom, a forward pole sectioncomrlsing a sheet metal cover, a wooden filler 1n the cover, said woodenfiller projected beyond the rear end of the sheet metal cover, and intothe hollow rear ole section, its top edge at the rear end being curvedand its lower edge straight, so that it may be extended a considerabledistance into the rear pole section without being bent, said sheet metalcover on the forward pole section being extended between the straps onthe rear pole section, and a bolt passed through said straps through thesheet metal cover, and through the-wooden filler.

2. An improved vehicle pole comprising a hollow rear pole section,curved upwardly and then forwardly from its rear end and formed withstraps on its forward end at its top and bottom, a forward pole sectioncomrlsing a sheet metal cover, a wooden filler 1n the cover, said woodenfiller projected beyond the rear end of the sheet metal cover, and intothe hollow rear pole section, its top edge at the rear end being curvedand its lower edge straight, so that it may be extended a considerabledistance into the rear pole section without being bent, said sheet metalcover on the forward pole section be in extended between the straps onthe rear po e section, a bolt passed through said strapsthrough thesheet metal cover, and through the wooden filler, braces at the sides ofthe pole, and bolts passed through said braces, one of them beingextended through the forward pole section, the other through the rearpole section, both bolts being extended through the wooden filler.
